The liver is the organ that makes proteins that clot the blood.
Reproductive success is defined as the passing of genes onto the next generation in a way that they too can pass on those genes. This is not solely the number of offspring produced by an individual, but also, as Ronald Fisher outlined in 1915, the probable reproductive success of those offspring, making mate choice (a form of sexual selection) an important factor in this success,[1] making biological fitness a key element in the theories of natural selection and evolution.
Explanation:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
The answer is B, carbohydrates.
Carbohydrates are the first choice of the energy source of your body, they can be broken down into simple and soluble compounds such as glucose. These can be used by cells for respiration to generate energy for activities such as growth, movement, repair etc. Besides using for respiration, they are also capable of forming cell structures such as cellulose.
Mitosis:Division of a parent cell, producing 2 identical daughter cells. (For growth and repair of body. Chromosome number remain the same in each cell.)
Metosis: 2 divisions of a germ cell, producing 4 non-identical gametes. (For genetic diversity in sexual reproduction. Chromosome reduce by half in each cell.)
Hope this helped, have a great day! :D
